Calibration Files

Unlike header, signal, and annotation files, calibration files are not associated with individual records. A calibration file is needed only if you have records containing signals other than ECGs; in this case, it is likely that a single calibration file will be adequate for use with all of your records. Calibration files are text files, with lines terminated by ASCII carriage-return/line-feed pairs, created by newcal, from which calopen reads the calibration list (see section 3.2 Calibration Information Structures). The WFDB Software Package includes a standard calibration file, `wfdbcal', in the `data' directory.
